Glass effect in ununtu like windows7

In Ubuntu you can set nearly the same aero glass effect to window borders with alpha transparency as available in Windows 7.

1. Press Alt+F2 to bring up "Run Application" window.
2. Type gconf-editor into the box, click "Run" to bring up Configuration Editor.
3. Browse to apps > gwd, look for "metacity_theme_active_opacity" on the right panel.
4. Change the value in "metacity_theme_active_opacity" from 1 to 0.75 (or smaller such as 0.5 for more transparency).
5. Then go to System > Preferences > CompizConfig Settings Manager
6. Select "Effects" from the left panel.
7. Tick "Blur Windows" and click the "Close" button. (Note: default values in Blur Windows can be applied.)

   If the aero glass effect doesn't work, check if you have updated your display driver. Go to System > Administration > Additional Drivers, activate the recommended graphics driver and restart the system.
